RESERVE TANK TRANSFER VALVE ADAPTER - REMOVAL/INSTALLATION
__________________________________________________________
1. General
_______
A. This procedure contains instructions to remove and install an adapter for the transfer valve in the reserve tank. The instructions are almost the same for all four of the adapters; only the locations are different.
B. NO. 3 RESERVE TANK INSTALLATION; The No. 3 reserve tank adapter plate is rotated 90 degrees on the rear spar. The OPEN and CLOSED indications must be read on the adapter plate when you use the manual position lever. Do not use the indication on the valve actuator.
NOTE: This installation allows the No. 3 reserve tank to open in an
____ inboard direction. This is necessary because ice can build-up in the transfer line outboard of the reserve tank transfer valve.
C. Two persons are necessary to do this procedure. One person is necessary outside the tank to remove or install the adapter shaft through the spar opening and to hold the adapter plate. And one person is necessary inside the tank to remove or install the mounting hardware.
D. The adapter for the reserve tank transfer valve is installed on the rear spar of the outboard main tank, below each transfer valve actuator. The adapter shaft goes through an opening in the spar and engages with the valve body.
E. The access for the adapters is behind the trailing edge flaps. You must extend the trailing edge flaps to get to the adapters.
